Bluetooth is well known to the public as a technology that provides a wireless link for local connectivity between a phone and a headset, or as a cable replacement. Its new extension, Bluetooth Low Energy (BLE) is a hallmark in the Bluetooth 4.0 specification adapted last year. As its name implies, BLE is intended for such energy-constrained applications as a sensor or a disposable device. BLE was designed to enable wireless connectivity with small devices running on a coin cell battery.
The LilyPad Arduino Main Board is based on the ATmega168V (the low-power version of the ATmega168) or the ATmega328V. The LilyPad Arduino was designed and developed by Leah Buechley and SparkFun Electronics.
This sensor will measure the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. New Features:
- Single supply - MyoWare won't need +/- voltage power supplies! Unlike our previous sensor, it can now be plugged directly into 3.3V through 5V development boards.
- Embedded Electrode Connector - Electrodes now snap directly to MyoWare, getting rid of those pesky cables and making the MyoWare wearable!
- RAW EMG Output - A popular request from grad students, the MyoWare now has a secondary output of the RAW EMG waveform.
Virtual reality (VR) is an increasingly common term to refer to the real-time computer-generated simulation of a three-dimensional environment that replaces the natural sources of stimulation of the real world by artificial stimulation in different channels. The extent to which an individual is unable to acknowledge that an experience is computer-generated, known as the level of presence, and other elicited subjective perceptions in VR are determined by user and media characteristics. User characteristics involve demographic aspects, motor or cognitive limitations, personality, and mood. Media characteristics involve not only the technological properties of the presentation of sensory information and the facilitation of the interaction, but also the content of the virtual environment (VE). The technology-mediated simulation of enriched environments and the provision of controlled sensory stimulation enable immersion in potentially hazardous and ecologically valid environments. These characteristics can be specially interesting for rehabilitation because they may allow to exceed the boundaries of the clinical setting and provide customized training to each participant.
